SPECIFICATION forming part of yLetters. Patent ivo. eligen, daten January c, 1899-. Application filed December 15, 1397. Serial No. 661,-935. (No model.)

TQ all whom it may' concern:

Be it known that I, WINFIELD S. THOMAS, of Boston, in the county of Suolk and State of Massachusetts, have invented a new and useful Improvement in Looms; and I hereby' declare that the following is a full, clear, and exact description of the same, reference being' had to the accompanying drawings, forming part of this specification.

This invention relates to improvements in shuttle-changing mechanism for looms, by

which when the weft-thread isexhausted or broken the shuttle is automatically discharged and replaced by another` shuttle.

In weavin g cloth the weft-thread is carried by the shuttle through the open-shed of the warp from oneside toI the other to lay the weft-thread, which when laidtilt-s the weftfork and raises the rear end above the wefthammer of the stop mechanism. When` the weft-thread is absent, the weft-fork is nottilted, the rear end engages with the said wefthammer, and in looms provided with automatic shuttle-changing mechanism operates the same to discharge the shuttle the fillingthread Of which is broken or exhausted and supply anew shuttle. The lay of a modern loom makes many strokes in a minute, and' I lower shaft of the loom in the manner-usual with stop-motions used on looms to stop the loom when the weft-thread is not laid, and in the same manner as is usual in these Wellknown stop-motions. p The said slide bears against an arm secured to and extending upward from the usual detectorrock-shaft, ex-

tending from side-to side under the breastbeam andsupported in suitable j ournal-bearings secured'to the breast-beam. .Near lthe opposite end of the detector rock-shaft an arm provited at its outer-end with an inclined cam operates a bellcrank lever, which as. the lay movcs away from the breast-beam uulocks4 the bottom plate or gate ofthe shuttle'- box on the lay, and the gate opens and ad'eiector connected with the gate enters the shut'- tle-'boz'i from above and guides the shuttle, which is tlirownfrorn the opposite shuttlebox by the picker-stick, downward into a suitable receptacle. An arm on the same end of the-detector rockshaft connected with a constantlyreciprocating arm operated.'

through a bell-crank lever from the lower or cam shaft raises the end of the constantlyreciprocating arm and connects it with a pin to operate the shuttle-carrier and swing the same toward the lay, so as to enter the uppermost shuttle into the shuttle-box, the gate of, which is being raised by a bell-crank lever,

and at the instant when the lay reaches the' limit ofthe .forward movement the bottom plate or gate of the shuttle-box is latched. As the lay swings backward the shuttle-carrier swings forward, and a shield covering the periphery of a ratchet-wheel secured to a shaft which forms the f ulcrum of the shuttle -carrier and provided with a sprocketwheel is moved to permit a pawl to enter the ,ratchet-wheel and turn the shaft, thereby communicatingmotion to the chain carrying the shuttles and moving the next shuttle into the upper position ready to enter the shuttle-box when required. All the parts of the vshuttle-supplying mechanism are now `again in their normal position ready to discharge a .shuttle the weft-thread of which may have broken or exhausted and supply a fresh shuttle.

Figurel is a side view of part of a loom, showing the crank-shaft, the lower or-'cam shaft, the lay, the shuttle-carrier, and the operative mechanism connecting the same. Fig. 2 is a front View of one end of the loom, showing the shuttle-supplying mechanism. Part of the breast-beam is broken away sO-.as to show-the mechanism behind the same more clearly. Fig.'3 is a transverse verticalsection of the front part of th'e loom, showing the mechanism connected with the detector rock-shaft and operated by the cam-shaft by which the shuttle-supplying mechanism is connected to operate automatically when the shuttle has failed to lay the weft-thread. Fig.

4 is a top orplan View of the front portion of Aone end of the loom, the crank-shaft being 'the shuttle-changing side of the loom.

omitted, so as to show the cam-shaft and the connections with the same more clearly. Fig. 5 is a top or plan view of the mechanism for actuating the shuttle-carrier and the shuttlesupporting chain. Fig. 6 is a top view, on an enlarged scale, of the rock-shaft by which the motion of the permanently-reciprocating arm is transmitted to the shuttlecarrier when the arm is raised and connected with the pin. Fig. 7 is a side View, on an enlarged scale, of the bracket supporting the shuttle-carrier and mechanism for operating the saine, shown also in Fig. 1. Fig. Sis a top View, on an enlarged scale, showing the shield covering the ratchetwheel and the lever for controlling the shield in the two opposite positions. Fig. 9 is a' side View, on an enlarged scale, of the ratchet-wheel connected with the shaft of the chain sprocket-wheel by which the shuttles are advanced, showing the pawl and the shield in broken and solid lines in opposite positions and above the same' the permanently-reciprocating arm and the pin on the rock-shaft, also shown in Fig. 6.. Fig. 10 is a vertical end viewshowing the mechanism for unlocking the bottom or gate of the shuttlebox and the swell mechanism connected with the gate and operated by the same in solid and in broken lines in opposite positions. Fig. 11 is a top or plan'view of the mechanism shown in Fig. 10. Fig. 12 is a vertical transverse sectional view of the breast-beam, the lay, and mechanism connected therewith, showing the lay in the position with the gate open when discharging a shuttle in solid lines and in the position when a new shuttle has aeen supplied and the gate locked in broken mes. tion of the breast-beam, the lay, and the mechanism for unlocking the bottom or gate of the shuttle-box. Y

Similar numerals of reference indicate correspondingparts in all the figures of the drawings.

In' the drawings the numeral 1 indicates the end frame of the loom; 2, the front strut, extending from one end frame to the other; 3, the breast-beam; 4, the crank-shaft, and 5 the lower or cam shaft; 6, the fulcrnm-shaft, on which the lay is supported; 7, one of the swords extending from the fnlcrum-shaft to the lay; 8, the lay, and 9 the pitman connect-` ing the lay with the crank of the crank-shaft.

In Fig. 12 the weft-fork 10 on the farther end of the breast-beam is shown pivotally connected with a slide 10', which when the. weft-fork is not tilted by the weft-thread is moved by the weft-hammer 102 and operates, through the arm 11, the detector rock-shaft 12, which extends under t-he breast-beam from one side of the loom to the other, the arm 13 secured to the detector rock-shaft at The inclined cam 14 on the arm 13 engages with a similar cam 1st on the bell-crank lever 15 and tilts the same against the strain of a coiled spring 142, connected with one arm of Fig. 13 is a plan view showing apor-` thc bell-crank lever to maintain the same in the normal position. The tilting of the bellcrank lever depresses the forward projecting arm 16, which at that instant of time has entered an opening in the lay and as the lay moves away from the breast-beam encounters with its inclined end the end of a pin connected with the latch 17, as is clearly shown in Fig. 13. The latch 17 serves to hold the gate 18, which forms the bottom'of the shuttle-box carried on the lay. The gate 18 is hinged on its rear side to the rod 18 on the shuttle-box and when released dropsdownward to open the bottom of the shuttle-box. The deiiector 19 is pivotally supportedon the shuttle-box above a slit 19', through which it may enter theshuttle-box. The tailpiece 2O of the dcliector 10 is connected to the slotted lever 21, journaled in a bracket extending above the shuttle-box. 'The lever 21 is provided with the swivel 22,and this is connected with the gate 18 by the connecting-rod 23, so that when the gate is unlatc'hed it swings -open and through the connecting-rod 23 and lever 21 raises the tail end of the deiieetor lil and carries thedeflector into the shuttle-box to guide the shuttle, which at this time is thrown from the opposite end of the lay downward to be discharged through the bottom and guided by the gate toward the breastvbeam into a suitable reeeptacleplaced below the shuttle-box.

The shuttle-box 24 is open on the side toward the breast-beam, and as the shuttles are inserted -into'the shuttle-box from this side the swell 25 is placed on the upper side of the shuttle-box and bears on the upperside of the shuttle, holding the shuttle in the shuttlebox during the backward vibration of the lay.

The lever 25, which controls vthe swell, vis pivoted in a bracket secured to the shuttlebox and has the opposite end connected by the link 26 with the rocking arm 27,tl1e forked end 28 of which engages with a 'pin on the arm 29 of the gate 18. vThe edge of the rock ing arm 27 near the forked end has the con- IOO IIO

cave 27 to correspond with the rounded ed ge 30 of the hinged sideof the gate 18, so that when the opening of the gate has carried the forked end 28 into the position shown in broken lines in Fig. 10 the rocking arm 27 will be retained -in this-position by the contact of the concave portion of the rocking arm with the convex edge 30 of the gate 18 with the end of the swell 25' raised and permits the gate to fully open. W'hen the gate is closing, the pin on the arm 29 enters the fork .28 and operates the rocking arm 27 and through the link 26 To secure this movement, thc gate 18 is provided with the roll-bearing 32, which as thc lay moves forward rides onthe arm 233 of the bell-crank lever 34. The end of the arm 33 is formed into a quick-rising cam 33', which acts to raise 'the gate to the locked position at the end of the forward movement. of the lay.

' The opposite end of the bell-crank lever 34 is the shaft 41.

provided with the heel-plate 35", having slots, and is secured to the slotted end of the bellcrank lever 24 by bolts, so that it may be adjusted vertically andhorizontally. `The heelr plate has the roller 30, which bears on the cam 37, secured to the cam -shaft 5. The shapeof the cam 37 is preferably such as will give to thebell-crank lever 34 and the gate 18, controlled by it, the desired movement to permit the entrance of a shuttle into the shuttle-box and the latching of the gate as' the lay, with the shuttle-box, moves forward.

The shuttlesv are supplied to theshultle box on the lay by the shuttle-carrier 38, consisting of a bracket.' supported onthe shaft 39. The upper partof the bracket is bifurcated, one part forming the journal-support of the shaft 40 and the other the bearings for These shafts are provided with sprocket-wheels 40 and 41', respectively, by which the endless chains 42 42 are operated.4 The links of the chains 42 42 are provided with spring-clamps 43on which the shuttles 44 44 are placed and are carried `successively forward until they reach the position ofthe shuttle 44', as shown in Fig. 1.' Ontheshaft 40 is also placed a sprocket-wheel 402, over vwhich passes the endless chain 45, extending over a sprocket-wh'eelj403, secured to the shaft 39, so that the turning of the shaft 39 transmits motion through the chain 45 to the chains 42 42 and to the shuttles carried on these chains. The shuttle-carrier 38 and the chains and shuttles carried by the 'same are given,l

when a shuttle is to be supplied tothe shuttlc-box yto replace the shuttle discharged, a swinging motion toward `the approaching shuttle-box on the lay. sufficient to carry the sh uttle into the shuttle-.boxand over the gate as the lay reaches the forward limit of its throw. The gate now swings upward 4and raises the shuttleoif from the shuttle-carrier and upward into the shuttle-box. When the gate is closed and latched, the shuttle-carrierV is made to swing forward to resume the normal position, as shown in Fig. l.

The mechanism for swinging the lshuttlecarrier 38 is operated bytv the cam 46,'secured to the camshaft 5. The bell-crank lever 47 is provided with a roll which bears on the cam 46. In the preferred form, as shownin Fig. 3, a grooved cam is used to controlthe bellcrank lever; but a spring may be usedin the usual manner to hold the heel of the bellcrank lever in contact with the cam. The arrn`48 is connected at one end with the bellcrank lever 47 and at ythe other end by the connecting-rod 4f) with the arm 50, secured to the detector rock-shaft 12 near 'the arm 13.

The arm 4S has near its forward end the seat 51 and ou one side of the seat the shoulder 52. W hen the detector rock-shaft is partially turned by the weftffork slide, the arm 50 raises theforward end of the arm 4S and the seat 51 engages with the crank-pin 53 and the backward movement of thearm 48 carries the pin 53 with it and partially turns by the crank 54 the sha-ft 55, to the opposite end of which the crank 56 is secured and provided with the crank-pin 57, which extends through a slot'in the plate 5S, secured to the shuttlefcal'rier 3S above the rocking support of the carrier on the shaft 39, thereby swinging the shutl.

carrier from its normal position, as shown in Fig. 1, and carrying the shuttle 44 inte the shuttle-box. As the detector rockfshaft resumes itsnormal position the arm 5 0 is lowered, the seat 51 is'disengaged from the pin 53, and the shoulder 52 bearson the pin 53 as the arm 4S .moves forward, thereby turning the shaft 55 and swinging the shuttle-carrier back into the normal position. The shuttle 44 having been placed into the shuttle-box, the chains 42 42 have to be operated to move the shuttles forward so as `to bring another shutt1e`into the position of the shuttle 44' by givin g to the shaft 39 a quarter-turn. To this end the ratchet-wheel 59, provided with four ypreferably hooked teeth, is secured to the shaft 39, thearin G0 is journaled on the shaft 39 close to the ratchet-wheel 59, the pawl (5l is pivotally and preferably ad j ustably secured to the arm 60, and to the arm is secured, in the vpreferred form adj ustably, one end of the rod 62, the other end o f which is secured to the bell-crank lever G3, the heel of which engages with the cam 64, secured to the camshaft 5, so that at each turn of the cam-shaft the pawl Gl will move forward, engage with a tooth, and in moving backward will-turn the ratchet-wheel 59 one quarter-turn, and with it the shaft 39, to operate the 'chain 45, and by it the chains 42 42 and the shuttles carried by them to advance the shuttles a distance equal to one shuttle.`

To regulate and control the forward' movement of the shuttles, the shield G5 is interposed between the pawl and the ratchet-tooth with which the pawl would engage were the shield removed. The shield is supported on the arm G6, counterweighted by the weight G7 and provided with a projection 67', coperating with the stop 68; adjustably secured to the fixed support of the shaft 39. In itsnormal position, as'shown in Figs. 2 and 9, the shield 65 covers one tooth and the pawl 61 rides on the shield. When the shuttle-carrier swings inward to carrythe upper shuttle into the shuttle-box, the lever 69, pivotally supported othe bracket 70, secured to the frame of the 105m, has the forked end 71 engaged with the pin 72'on the shuttle-carrier 38, and the .oppo-` site end','provide with thel spring-pawl 73,

'is moved into th position shown in broken lines when the shuttle-carrier swings inward to place a shuttle 'into thc shuttle-box and IIO 'pawl, which has yielded to and passed over the projection 74 on the shield 65, engages with the same and carries the shield over the tooth of the ratchet-wheel 59 and permits the pawl 61 to engage with the tooth to turn thek shaft 39 and operate the chains to move the shuttles 44; forward. As the shaft 39 must be turned exactly one-quarter turn to move the advance shuttle into the exact position required .to carry it into the shuttle-box and' raise it out of the spring-clamps '43 by the closing of the gate 18 of the shuttle-box, and as themechanism for operating the shaft 39 is liable to wear, I secure to theshaft the disk 75, having at equal distances apart four concave seats 7 6, and pivotally secure to the arm 77 of the bracket 78 the lever-arm 79, provided at its lower end with the roller 80, the peripheral surface of which coincides with the concave seats 76, and I also secure the coiled spring 8l at one end tothe leverarm 79 and at the other end to a fixed part of the machine. The spring Sl is of sufficient strength to force the roller 80 into the concaved seats 76 when it has partially en'- tered the same, and thereby overcomes any wear or backlash in the operating mechanism.

I-Iaving thus described my invention, I claim as new and desire to secure by Letters Patentl.
